| Alloy | Alloy Series | Main features |
| 2B16 | Al-Cu-Mn | The heat treatment strengthened alloy, Al-Cu-Mn rivet alloy, is used for riveting the aeronautical spacecraft. It has good riveting performance, and it can work for a long time below 250 degrees. Its room temperature and high temperature shear strength is higher than that of 2A10 alloy. It can be used for a long time after heat treatment. The supplied wire is 1.6~10mm in diameter and is delivered in a cold hardened state. The rivets are used to riveting heat resistant structures of large missiles, large launch vehicles and aircraft after solid solution treatment and artificial aging. |
